I don't know since which update it's appearing.
But now the improvised shelter kit (and tents too) is impossible to deploy in places which it is supposed to be made for.
The main purpose of an improvised shelter is to be hidden in the woods. Some update ruined this purpose, making improvised shelters useless.
I was used to place a shelter between two pines, making it very hard to spot. Now I cannot place a shelter less than 2 meters away from a pine making it extremely visible and useless.
And in general, these improvised shelters and small tents are designed to be set up in wild places, not on a super flat parking of a city, that's not the purpose of it.
My suggestion is to allow deployment of tents and shelters on accidented or sloping grounds because that's the purpose of an improvised shelter.
